This is known as a Tyrolean hat and was bought in West Germany. Many men is Germany and Austria wear these hats. It is made of a very war felt and it a deep green color. This was my dear dad’s hat and I would love it to go to someone who will love it. It is a bit dirty but I don’t know how to clean it. If you do, great. I guess maybe a cleaners if you don’t know. The inside brim is 22 inches.
